Sulfonated Asphalt


Sulfonated asphalt contains sulfonic groups and has a strong hydration effect. When adsorbed on the shale interface, it can prevent the hydration and dispersion of shale particles and play an anti collapse role. At the same time, the insoluble part can also fill the pore throat and crack to play a sealing role and can cover the shale interface, improving the quality of the mud cake; Sulfonated asphalt also plays a role in lubricating and reducing high-temperature and high-pressure filtration in drilling fluids. It is a multifunctional organic drilling fluid treatment agent that can block leaks, prevent collapse, lubricate, reduce drag and inhibit.

Standard: Q/SY 17095-2016
